Tucked behind a sun-drenched illustrated scene of a rosy-cheeked couple lounging against a haystack — bicycles propped nearby, a cheerful bird perched in a golden sky — is one of French postal culture's most charming parlor tricks: a concertina pull-out accordion strip revealing miniature black-and-white photographic views of Reims unfurling from the card's lower edge. The front caption reads Couchés dans le foin… Sous la meule vous verrez Reims ("Lying in the hay… Under the haystack you will see Reims"), a knowing wink to the viewer that the card hides a souvenir inside. The accordion strip, accessed by lifting the illustrated flap at the bottom, contains multiple miniature views of Reims landmarks including what appears to be the famous Gothic cathedral façade, the Hôtel de Ville, and city vistas — all rendered in crisp photographic half-tone. Published by Éditions Gaby (fabrication française, G. Artaud, Avenue de la Close, Nantes), this is a classic mid-20th-century French novelty mailing card numbered 452 on the reverse, filed here as No. 452 in pencil.
